Here's my opinion.... I swing both ways!
Kinda like Austin's been saying...there are certain groups that just HAVE to do it! Rick Nielsen's with his strangely different guitars (do they actually make different sounds or are they just for show?), Angus with his lighted, rising stage or Tommy Lee in a pair of Speedo's
with his spinning drum kit overhead. But in my opinion--these bands and performers have talent to go along with all the special effects.
But as Soda mentioned, performers (I use the term loosely) like Lady Gaga, I feel are doing it more because there isn't much talent to fall back on if you don't have the special effects to go along with it.
Then their are groups like the Eagles, that I'd rather just hear the music and sure don't need or want anything to distract me from that.
So that all being said, maybe we should add another poll choice of "I swing both ways" or such.
